Or maybe people should avoid using ellipses?  ;-)

I don't either.

I would even say "more than needed".  ;-)  I'm not sure many people would
be willing to specify this sort of parameter by hand, for each and every
character.

Another solution might be to add heuristics to avoid margin-kerning
glyphs that are "unreasonably wide".  "Unreasonably wide" could be
defined as "wider than `x'" for instance.  This same heuristic could be
applied to subsequent characters also.  For instance, a quote followed
by a comma may be narrower than `x' and therefore eligible as a whole
for margin kerning.  On the contrary, the ellipsis glyph may be too wide
and will never be margin-kerned.

I'll give it a try unless you think it doesn't make sense.

Thanks,
Ludovic.
